As businesses scale, cloud security should be on the forefront of everyone’s mind when operating in the cloud. The cloud makes it increasingly easy to deploy resources, which can easily lead to internal misconfigurations and data breaches. Creating a strong cloud security team can help prevent these mistakes from happening.
Why is cloud security important?
Cloud security is a set of company policies and processes implemented to protect data and infrastructure resources in public clouds. Cloud security requires collaboration between departments and teams to address emerging security and compliance issues that organizations face.
Cloud security isn’t easy. They need to achieve properly configured services to encrypt data, prevent unauthorized access to resources, and maintain regulatory compliance—all without slowing down innovation.
Creating a cloud security team allows organizations to prevent accidental misconfigurations that can lead to data exposures, financial losses, and erosion of brand value for companies. However, if your company is small, or you’re just starting your cloud security path, you may not be able to create a large security team right away and can only dedicate one team member to cloud security. This team member is more commonly known as the cloud security architect and they can provide valuable skills when building out your cloud security function.
What is a cloud security architect?
Creating a Cloud Center of Excellence (CCoE) can help create clarity around shared responsibility on the customer side. The CCoE needs a cloud security architect who is extremely skilled in security and cloud technologies in order to provide secure and compliance solutions that enable different information security teams to perform their responsibilities and coordinate efficiently.
A cloud security architect works closely with IT operations, developer teams, and cross functionally to establish best security practices, enable auto-remediation, and decrease security threats across the organization. The cloud security architect is an important player on the cloud team, and can help drive collaboration across an organization.
Maturing your multicloud security
Your CCoE and cloud security architect will work together to start to maintain and mature your mutlicloud security function.
1. Get visibility into cloud accounts and security vulnerabilities
The first step to maturing your cloud security function is to gain visibility into all cloud accounts. Creating a coordinated approach for access management, collecting inventory data, and standardizing creation of new accounts can help increase visibility.
By getting access into these cloud accounts, conducting a first time security assessment is recommended with out-of-the-box assessments. Be prepared to be flooded with security violations and alerts, but don’t change notification preferences just yet because you’ll want to maintain real-time visibility into these accounts. Once you have visibility into what your cloud environment looks like, then you should develop a notification process (i.e. severity of alerts, frequency, approval chains, etc.) that works for your organization.
2. Optimize security control based on organizational requirements
After getting some insight into the types of security violations your company has experienced, it’s time to cut it back and identify an optimized set of controls to minimize false positives. These controls depend on application, business, organizational, or industry context. Start with a smaller set of controls based on these needs, work with developers to resolve violations, and gradually add additional controls overtime.
3. Improve governance by automating actions
Once controls are set in place, businesses can improve their threat detection and free up time for the outnumbered security personnel by using auto-remediation. Violations can be broken down into easily automated tasks and ones that need human remediation. Knowing which threat falls into each bucket is helpful when creating guardrails and policies. Developer intervention is typically needed for violations, but finding the areas for automation resolution is key.
4. Integrate security proactively in application deployment process
This step can be achieved by building security checks into the CI/CD pipeline, so when a resource is created, security is already monitoring misconfigurations at the time of deployment. This then creates a continuous feedback loop for security teams of threat detection. This feedback can be changed depending on department/application needs, but should constantly be monitoring for configuration drift.
All in all, security is a key part of a multicloud environment and cannot be ignored. The security team should work to appeal to all stakeholders, achieve real time security insights, and prevent cloud security breaches. Developing your cloud security function takes time, however it doesn’t have to with CloudHealth.
